Application filed September 6, 1919. Serial No. 322,127.

To all whom it may concern:

Be it known that I, DAVID BAUM, a citizen of the United States, and a resident of Livermore Falls, in the county of Andro scoggin and State of Maine, have invented glove turning machines, an object ofthe in vention being to provide improved meansfor quickly turning a glove rlght-side-outor wrong-side-out as the case may be, and which operation is entirely automatic...

Gloves, and particularly cheap gloves of cotton, canvas and similar woven material, are made wrong-side-out and must be turned right-side-out before forwarding to the trade. It is the purpose of my invention to provide a machine, which at each complete operation, quickly and efliciently performs the function of reversing the glove; that is to say, turning it right-side-out .ready for the trade.

A further object is to provide improved means for supporting the glove and improved means for causing the glove to be reversed.

A further object is to provide an improved arrangement of finger and thumb supports which receive the fin ers and thumb of the glove and which glove in position and assist in the'reversing operation.

A further object is to provide an improved arrangement of thumb support which can be shifted from one position to another to accommodate both right and left gloves.

A further object is to provide improved means for gripping the glove and turning it while the fingers are being held and provide means for controlling all of the operations of the machine so that each opera:

tion will be timed and function in proper order.

\Vith these and other objectsin view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view in side elevation illustrating my improvements;

Fig. 13 is a view in longitudinal section of a modified form of fin er support; and

Fig. 141s an end View or'ri s.

1 represents a. standard having a supporting bracket 2 fixedthereon and a vertically movable bracket 3. A drive shaft 4 is mounted insuitable bearings 5 at the upper end of standard 1 andhas a drive pulley 6.connected thereto by means of a single revolution clutch 7, the latter operated by a rod 8 in the ordinary way to permit a single revolution of the shaft and a complete operation of the machine, which will be more fully hereinafter described.

A crank arm 9 is provided on the shaft 4 and is connected by a link 10 with the bracket 3 so that the bracket is'given a complete downward and upward movement The bracket 3 has a dove-tailed recess 11 in its inner end receiving a dove-tailed guide plate 12 on the standard 1 and a strip 13 is interposed between the edge of plate 12 and the wall of recess 11 to insure a perfect engagement and to take up wear.

A bed plate 14 is secured on bracket 2 and is provided with screw threaded openings 15 to receive finger tubes 16, 17, 18 and 19 which are screwed into the openings 15,

as indicated clearly in Fig. 10. I call these 100 parts 16, 17, 18 and 19 finger tubes because they are adapted to receive the fingers 20.

of a glove'21 thereon, and, hence, these and is mounted to turn freely around they 110 glove during the tube 16. This-pinion 24is in mesh with a gear wheel 25, the latter mounted on a post 26 secured to the bed plate-14 and bracket 2 by means of a screw 27. A housing 28 covers the gear wheel 25 and a forked strip 29 is located under the housing and projects into an annular groove 30 in the link 22 above pinion 24 to prevent vertical movement of the link andthe thumb tube 23 carried thereby.

A pinion 31 is fixed to turnwith gear wheel 25 and is operated by means of a rack bar 32, the. latter mounted to move in a recess 33 in bed plate 14. A lever 34 is pivotally supported between its ends on the bracket 2, as shown at 35, and the upper end of the lever 34 is pivotally connected to the rack bar 32 by means of a pin 36. An enlargement 37 is provided on the lower end of the lever 34 and is adapted to be engaged b the knee of the operator to swing the thum tube from one extreme position to another so as to accommodate right and left gloves, as will be understood. v

The vertically movable bracket 3 supports six plungers 38, 39, 40, 41, 42 and 43 respectively. T he plungers 38, 39, 40 and 41 are adapted to enter the finger tubes 16, 17,. 18 and 19 while the plungers 42 and 43 are ada ted to enter the thumb tube 23.

hese plungers are positioned in bosses 44 on the bracket 3 and are secured by means of nuts 45, as clearly shown.

A pair of guide sleeves 46 and 47 are secured in bosses 48 on bracket 3 and have forked lower ends 49 carrying pivot pins 50. These pivot pins 50'are projected through the intermediate portions of crossed grip- P1I17g levers and 61 respectively.

ertically movable rods 52are mounted to move in the sleeves 46 and are made with toothed racks 53'at their upper ends and mesh with pinions 54. Cross heads 55 are provided on the lower ends of the rods 52, and links 56 and 57 'respectivelyconnect the ends of the heads 55 with the gripping levers 61 and 60 respectively. The links 57 have slot and pin connections 51 with the gripping levers 61 to permit of a certain ,amount of lost motion for a purpose which will hereinafter appear.

The levers 60 have recessed ends 58 to conform in shape to the glove around the tubes and the levers 61 have toothed ends- 59 to grip the glove during the turning operation.

' The pinions 54 operating the racks 53 are fixed to turn with pinions 62 on shafts 63 and are supported in proper position by spacing'sleeves 64.

A racklbar 65 is mounted to slide on the bracket 3 and is in mesh withboth of the pinions 62. A coiled spring 66 is'connected at one end to a pin 67 on the'rack bar 65 and at its other end to a pin 68 on the racket ,v

thus exertin a continuous inward pressure on the rack ar.

A bracket 69 is connected b a pivot pin 70 with theinner end of rac bar 65 and weak springs 71 are located around the pins Y70 and exert a pressure on the bracket 69 tending to hold the bracket in alinement with the rack bar 65. A roller 72 is carried by the bracket 69 and engages a cam strip 73 fixed to the plate-12 and having a beveled lower end 74 located in a recess 75 in the said plate 12.

Any desired'number of finger tubes ma be provided with grippers 76 and 77, whic are located inside of the tubes and pivotally supported between their ends, as shown at '78. These grippershave teeth 79 on their inner faces at their upper ends and their lower ends are pressed apart by'springs 8O which'tend to forcethe teeth 79 toward each other to grip the inwardly forced glove finger, as will be understood. The teeth 79 are beveled so as to permit the ready inward .movement of the finger by, means of the plunger and serve to grip the finger when the plunger is withdrawn.

The tubes are provided with slots 81 to accommodate the movementof the rippers. In the modification illustrated in igs. 13

and 14 a plurality of spring grippers 82 constitute the upper endof the finger tube 83 and said grippers have a sufficient inward pressure at'their upper ends 84 to grip this glove finger when it is turned inwardly.

vA glove ejector-85, which constitutes a wire or rod, is supported ona fixed rod 86 extending outwardly from the standard 1 and a spring 87 engages the'ejector and tends, to force the lower free end thereof forwardly. During the greater .portion of movement of the bracket 3, however, the plunger is held in a rearward position by reason of the cam action of a shoulder 88 on the bracket, but when the bracket reaches its highest position. the ejector can move forwardly and throw the glove outwardly, as will be explained.

The operation of my improvedmachine is as follows: Fig. 1 shows'the position of the glove 21 on the finger and thumb supporting tubes and this operation of placing the Y glove is done by hand. As the bracket 3 moves downwardly, the plungers 38, 39, 40

and 4l will enter the finger tubes 16, 17, 18 and 19 and in doing so will press the fingers 20 of the glove21 into the tubes. At the same time, of course, the plunger 42 forces the thumb of the glove into the thumb tube I 23; During this downward movement of the bracket 3 the grippers 60 and 61 are in an inoperative position because the bracket 69 on the end of rack bar 65 is positioned at an upward angle by reason of the engagement of the roller 72 with the straight edge a downward movement of the bracket 3 gives clearly shown in Fig. 5.

good results.

of the strip 7 This first or initial position of the. parts is illustrated in Fig. 3. p

The next position of the parts isindicated in Fig. 4, in which it will be noted that the bracket 3 has moved downwardly'tar enough to allow the pivoted bracket 69 to'mo've into the recess 75 and hence, thesprings71 have forced the bracket 69 into a position alinement' with the rack bar 65. This [is the extreme lower position of the upper'bracket.

As the bracket then moves upwardly to the position shown in Fig. 5, it will be'noted that the rack bar 65 has'been caused to move to the right ofthefigure by' reason of the roller 72 which is against the" edge of strip 73 and has mounted-to this position along the beveled edge 74. This movement of the rack bar 65 brings the gripping levers '60 and 61 into operation causing their free ends to grip the wrist portion of the glove, as

It will also be noted inth'is figure that the grippers 76 and 77 are gripping the inwardly projecting portions of certain of the glove fingers and, as above stated, lmay employ any desired number of these internal grippers, but have found that the provision of two pairs of these grippers will perform Fig. 6 illustrates" a; further' u ward position of the bracket?) in which it will be seen that the glove has been completely turned and the fingers thereof are being drawn out ofithe. finger tubes. The'gripping levers 60 and61 will holdthe glove and continue to hold the same until the I glove fingers are free from the tubes and until the bracket 3 comes to a jrest after the, crank arm 9 has passed slightly over its center and caused a slight downward movement of the bracket 3. This slight an upward tilting movementto the bracket 69 when the spring 66 complete's this movement to the position shown in Fig. 7 and causes the grippinglevers 60 and 61 to Irelease the glove, as shown clearly in Fig. 7

At this time the ejector 85 swings forwardly and throws the glove out of the way,

A slot and pin connection 51 "between link 57 and lever I 61 permits a certain amount of lost motionso that'the lever 60 comes into operation or position beforethe lever 61 begins to move. Hence, the lever 00 engages under, the wrist portion of the glove and slightly wrinkles the same before the end of lever 61 move's'downwardly to grip, thematerial, thus insuring a tight gripping action to cause the turning of the glove when the grippers move upwardly and to overcomethe'holding action of the internal grippers, in the tubes to"pull"tl1e' glove free from the same after the turning" operation is complete.

plungersmovable into the tubes to a" glove When it is desired to shift the thumb tube so as to operate on rightor left hand gloves,'*as 'the case'may be,-1t is simply necessary to swing-the lever 34. Thisoperation can be readily performed by the leg or 'knee of the operator.

Various slight changes may be made in the general form and arrangement of parts described without' dep'arting from the inventiom and hence I do'not limit myself to the" precise details set forth but consider myself at libert to make such changes and alterations as airlyfall within the spirit and scope-of the appended claims.
